Problems solved by technology

[0002] With the development of hydrogen fuel cells, more and more attention has been paid to the performance testing of hydrogen fuel cells. The overall performance of the fuel engine is closely related to the performance of the fuel cell. However, the existing test methods only focus on the performance indicators and service life of the fuel cell. Testing is used to judge the overall performance of the engine. This method cannot fully obtain the performance indicators of hydrogen fuel cells. The economic performance of hydrogen fuel cells, actual operating conditions and related tests in specific environments need to be further improved. , so the present invention provides a comprehensive and comprehensive method for testing hydrogen fuel testing
